If you install GFI MailEssentials on a separate machine that is not your gateway SMTP server, you must ensure that you configure the Perimeter SMTP Servers option in the GFI MailEssentials configuration after you finish the installation. The perimeter SMTP server is the gateway SMTP server which receives your emails directly from the internet and you will have to specify the IP address of your perimeter SMTP server in GFI MailEssentials, especially if you are going to use the SPF filter feature. For more information on how to setup your gateway SMTP server, please refer to the ‘Defining your Perimeter (Gateway) SMTP Server’ section of the ‘Configuring Anti-spam’ chapter in this manual. Effectively GFI MailEssentials will act as a mail relay server between the perimeter (gateway) SMTP server and the recipients’ inboxes.
NOTE 1: GFI MailEssentials currently cannot be installed on a Windows Server 2003 x64 Edition machine, if Microsoft Exchange Server 2007 is not installed on that machine.
NOTE 2: Since the version of Internet Information Services (IIS) included in Windows XP is limited to serving only 10 simultaneous client connections, installing GFI MailEssentials on a machine running Windows XP could affect its performance.
NOTE: If you are going to install GFI MailEssentials on the Microsoft Exchange 2007 Edge Transport Server Role, you do not need to install the IIS SMTP service since Microsoft Exchange Server 2007 has its own built in SMTP server.

For list server only: The list server feature requires the installation of Microsoft Message Queuing Services. This is a scalable event processing system service developed by Microsoft. It is included with every Microsoft Windows 2000/2003 version, although not always installed by default. For more information on how to install it, please see the chapter ‘Configuring the list server’. If you do not plan to use the list server feature, you do not need to install Microsoft MSMQ.

IMPORTANT: Disable anti-virus software from scanning the GFI MailEssentials, Microsoft IIS, and Microsoft Exchange Server directories. Anti-virus products are known to both interfere with normal operation as well as slow down any software that requires file access. In fact, Microsoft does not recommend running file based anti-virus software on the Microsoft Exchange Server. For more information read the following article: http://kbase.gfi.com/showarticle.asp?id=KBID001824
IMPORTANT: Make sure that backup software is not backing up any of the GFI MailEssentials directories at any point.
NOTE: If you have a Microsoft Exchange Server 2007 environment and are going to install GFI MailEssentials on the Microsoft Exchange 2007 Edge Transport Server Role machine, you do not need to install or configure the IIS SMTP service since Microsoft Exchange Server 2007 has its own built in SMTP server.
NOTE: If you have a cluster please check this Knowledge Base article prior to installing GFI MailEssentials: http://kbase.gfi.com/showarticle.asp?id=KBID001639
1. From the Start menu access the Control Panel.
2. Open the Add or Remove Programs and click on the Add or Remove Windows Components.
3. Click the Internet Information Services (IIS) component and click the Details button.
4. Verify that the SMTP Service checkbox is selected. If it is not selected, click it to select it.
5. Click the OK button, and then follow the installation instructions that are displayed.
1. From the Start menu, access the Administrative Tools.
2. Click on the Internet Information Services (IIS) Manager icon.
NOTE: During installation, GFI MailEssentials will perform this step for you automatically. GFI MailEssentials will ask for your local domain name, and create it as a remote domain. You will see the domain listed in the right pane. However, if you do this step manually, you can confirm that your relay server is working properly before running the GFI MailEssentials installation.
Click the Start menu, point to Programs, click Administrative Tools, and then click Internet Services Manager.
Expand the tree under the server name, and then expand the Default SMTP Virtual Server. By default, you should have a Local (Default) domain with the fully qualified domain name of the server.
1. Right click the Domains icon, click New, and then click Domain.
2. Click Remote, click Next, and then type the domain name in the Name box. Click Finish.
NOTE: Upon installation, GFI MailEssentials will import inbound email domains from the IIS SMTP service. If you want to add additional inbound email domains, you have to add these domains in the GFI MailEssentials configuration. For more information, see ‘Adding additional inbound email domains’ in the ‘Miscellaneous options’ chapter.
1. Access the Properties dialog for the domain that you just created and check the Allow the Incoming Mail to be Relayed to this Domain checkbox.
3. Click the Forward all mail to smart host option, and then type the IP address of the server that is responsible for email for that domain in square brackets. For example: [123.123.123.123]
NOTE: Typing the IP address of the server in brackets is necessary so that the server recognizes that this is an IP address, and thus avoids any attempts at performing a DNS lookup.
1. Open the Properties of the Default SMTP Virtual Server.
2. On the Access tab, click Relay.
3. Click Only the list below.
4. Click the Add button, and then add the IP of your mail server that will be forwarding the email to this server. You can specify a single computer, group of computers or a domain:
Single computer - Specify one particular host that you want to relay off from this server. If you click the DNS Lookup button, you can lookup an IP address of a specific host.
Group of computers - Specify a base IP address for the computers that you want to relay.
Domain - Select all of the computers in a domain by domain name that will openly relay. This option adds processing overhead, and might reduce the SMTP service performance because it includes reverse DNS lookups on all IP addresses that try to relay, to verify their domain name.
2. Go to the Internet Mail Service and double-click on it to configure its properties.
3. Go to the Connections tab.
4. In the Message Delivery section, select Forward all messages to host. Enter the computer name or IP of the machine running GFI MailEssentials.
5. Click the OK button and restart the Microsoft Exchange Server. This can be done from the services applet.
2. Right click on the Connectors Node, select New > SMTP Connector, and then create a new SMTP connector. You will be prompted for a name.
3. Select the option Forward all mail through this connector to the following smart host, and type in the IP of the GFI MailEssentials server (the mail relay server) enclosed within square brackets, for example: [100.130.130.10].
4. Click Add in the Local bridgeheads section, and select the appropriate virtual SMTP Server instances that you want to forward email for.
5. Go to the Address Space tab, and click the Add button. Select SMTP and click the OK button.
6. Click the OK button to exit. All emails will now be forwarded to the GFI MailEssentials machine.
NOTE: If you wish to send out email using a smart host (used when using dial-up) or receive email using ETRN, you will need to perform additional steps to configure IIS 5 as a mail relay server. For more information, refer to the IIS 5 documentation.
NOTE: Instead of using an email client, you can use Telnet and manually send an email. This will give you more troubleshooting information. Here is the link to the Microsoft KB article on how to do it:
NOTE 1: If installing on Microsoft IIS SMTP (x86), Microsoft Exchange Server 2000, or Microsoft Exchange Server 2003, then you need to run the x86 version of GFI MailEssentials 12: mailessentials12.exe
NOTE 2: If installing on Microsoft Exchange Server 2007, then you need to run the x64 version of GFI MailEssentials 12: mailessentials12_x64.exe
NOTE: If you are installing GFI MailEssentials on a Microsoft Exchange 2007 Edge Transport Server Role machine, the inbound email domains step of the installation wizard is skipped since these are determined from the GFI MailEssentials Post-Installation wizard that is launched when you finish this installation wizard.
NOTE 1: If you are installing GFI MailEssentials on a x64 machine with Microsoft Exchange Server 2007, the files will be installed under the c:\program files (x86)\ folder.
NOTE 2: If you are installing on a Microsoft Exchange 2007 Edge Transport Server Role machine, you will not be prompted to restart the SMTP service.
NOTE: If you are installing on a Microsoft Exchange 2007 Edge Transport Server Role machine, the installation will launch the GFI MailEssentials Post-Installation Wizard. Refer to the following section for information on how to use this wizard.
